Dear Colleagues,

It looks that some worked targets will be done soon, with only one or two
more sessions.  Others are no longer reachable for some of you, or 
critical phases in them don't occur during your observing windows.
So, it has come a time to provide you a new list of targets.
Before you start a new target from the list in section 5 below,
please first check whether you cannot contribute to some of the higher
priority targets in sections 0 to 2 (also don't forget to check their
status in the binast-webtool).

Enjoy.

This list of targets is also available on
http://www.asu.cas.cz/~asteroid/binastphotsurvey_listoftargets20090402.txt

Clear Skies,

Petr Pravec

                        Binary, one good long session for each of the

                        secondary event may suffice to nail down its D2/D1.

Note: The ephemerides were computed for 2009-04-02
      ^/v means that the value increases/decreases by more than
      0.05 mag/day (for V) or by more than 0.5 deg/day for Dec and Elong.
      The rate of apparent motion (Mot) is in deg/day.
      Bga is the galactic latitude.
